Plotted to give you a sense how the seasonality in GPP in some of these systems as well as what times of year we have data for each lake.
Code not printed.
Southern hemisphere and lakes in Asia not printed on a map, but note that they do exist!

Showing you how many lakes (n, as well as percentage) where we can get “true” load estimates from stream discharge and nutrient grab samples
Here I’m showing a few figures to give you a sense of the lake size distributions, both categorical and continuous.
Here I’m showing a few figures to give you a sense of the HRT distributions. These HRT estimates were either given to me by the folks sharing data, or I extracted them from the literature. Still missing a few lakes.
Data wrangling, not shown.

We also have some other nutrient data for some lakes, but it is much less consistent. For instance, we have some absorbance data, but not always measured at 440nm. Some folks also supplied dissolved nutrients, and I believe all the particulate nutrients come from UNDERC lakes.

At our meeting last week someone mentioned something about comparing the Kelly model calculated zMix values (Equation 7 from the paper) with modeled zMix values. This is how it looks. We don’t have a lot of chla or POC data, which might be one reason this looks off.
